Determine metal needed from pattern
Pattern displaced 367g of water. So volume is 367cc.
Aluminum weighs 2.7g per cc.
2.7 x 367g = 1015.2g
Determine how much metal the flask can accommodate
Flask diameter is 4"
Safe fill is about 3.5" with 1/2" below top
Flask volume is pi r squared x height.
pi x (2x2) x 3.5 = 43.96 ci
43.96 ci x 16.387 = 720 cc
720 cc x 2.7 g/cc = 1944g
Looks like I have a nice margin.
